Setting up
The Water Computer may only be set up
vertically with the sleeve nut to the top to
prevent water penetrating into the battery
compartment.
The minimum water output to ensure that
the Water Computer functions correctly is
20 - 30 l / h.
For example, at least 10 x 2-litre Drip
Heads are required to control the Micro-
Drip-System.
At high temperatures (over 60 °C at the
display) the LCD display may extinguish.
This does not affect the program in any
way. When the computer cools down the
LCD display illuminates again.
